High Performance H13 & SKD-61 Ejector Pins | The Optimal Solution for Moulds

The detail information of product

VINACNC - High-Quality, Hot-Selling H13 and SKD-61 Ejector Pins

In the mould industry, the ejector pin is a core component that determines the precision and efficiency of the part ejection process. VINACNC is proud to supply H13 and SKD-61 ejector pins with high hardness and tight tolerances, ensuring superior performance and durability even under harsh production conditions.

Technical Specifications, Materials, and Applications

Material: The products are crafted from high-quality tool steels:
- H13 Steel (AISI/SAE): Known for its high-temperature resistance, hardness, and strength, ideal for die casting applications.
- SKD-61 Steel (JIS): A widely used tool steel with good hardness, durability, and heat resistance, suitable for both plastic injection and die casting moulds.
Technical Properties:
- Hardness: After heat treatment, the material achieves a stable hardness (typically HRC 48-52°), allowing the ejector pins to withstand high pressure and friction during continuous operation.
- Precision: The products are machined with extremely tight diameter tolerances, ensuring a perfect fit with the mould, preventing plastic leakage, and guaranteeing the accuracy of the final product.
- Surface Finish: The surface is specially treated to achieve high smoothness, which reduces friction, ensures a seamless ejection process, and extends the lifespan of the components.
Applications: H13 and SKD-61 ejector pins are indispensable components in plastic injection moulds and die-casting moulds for complex, high-durability parts such as automotive components, electronic device housings, and industrial products.

Product Advantages

Superior Durability: With high-quality H13 and SKD-61 materials, the ejector pins resist repetitive force and pressure during production, extending the mould's lifespan.
Absolute Precision: Dimensions are strictly controlled down to the micrometre level, ensuring the components operate in perfect conjunction, minimizing the risk of plastic leakage and product defects.
Optimized Performance: The smooth operation helps to reduce the moulding cycle time and enhances overall production efficiency.
Competitive Pricing and In-Stock Availability: Thanks to our optimized production process and extensive experience, we can offer products at a great price, and with a large inventory of standard sizes, we can quickly fulfill orders.

Post-Machining Product Inspection Process

Hardness Test: We use a professional hardness tester to verify the hardness of the heat-treated material, ensuring it meets technical specifications.
Dimensional and Tolerance Check: We use a Coordinate Measuring Machine (CMM) or other high-precision measuring instruments to check the diameter, length, and concentricity.
Surface Inspection: We use a surface roughness tester and visual inspection to ensure there are no cracks, scratches, or other defects.
Functionality Test: The components are test-fitted with related parts to ensure a perfect fit and smooth operation.

Packaging and Storage Process

Cleaning and Rust Prevention: The pins are cleaned and coated with a specialized anti-rust oil to protect their precision surfaces.
Secure Packaging: Products are carefully packed in rigid plastic boxes or cardboard crates with foam to prevent damage during transport.
Information Labeling: The packaging is clearly labeled with the product code, weight, dimensions, and handling instructions.
Storage Instructions: We recommend storing the products in a dry, cool environment, away from high humidity and corrosive chemicals.
